Even though the Emma mattress and the Simba mattress are both high-quality choices, they are very different in composition.

The Simba mattress is a hybrid model that combines conical mini pocket springs with multiple layers of foam, while the Emma Original is largely a memory foam mattress.

Simba Hybrid mattress
The Simba mattress combines pocket springs with foam.

Interestingly, Simba used to be a pocket-sprung memory foam mattress, and the older version featured a layer of memory foam and a layer of latex foam, making it more similar to the Emma Original.

The composition of the Simba has since gone through multiple changes - the latest model is both more breathable and more eco-friendly.

The mattresses are suitable for different types of people, which is something we'll look at in more detail next.

Emma vs Simba: Which mattress is best suited to you?

Simba or Emma mattress?

The Simba Hybrid and Emma Original mattresses are both very comfortable, but they're suited to very different types of people.

The mattresses have different compositions that highlight unique features.

Both, though, are excellent choices if you're looking for something more environmentally friendly. 🌱

The Emma Original and the Simba Hybrid are both free from harmful chemicals and toxins and adhere to UK fire regulation BS7177 [1].

Simba Hybrid: superior support and breathability

Both the Simba and the Emma are rated as medium-firm mattresses, but we found the Simba to be slightly softer, and have placed it at 6 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.

We've found that the Simba mattress offers excellent support, even pressure distribution, and optimal spinal alignment regardless of which sleeping position you prefer.

It is particularly comfortable if you sleep on your back, but is also highly recommendable to side sleepers. 😴

This mattress also offers excellent edge support, meaning that you can use the full width of the mattress without ever feeling like you're falling off the sides.

It's also easy to move around on, making it suitable for restless sleepers.

Finally, the Simba Hybrid has been designed with breathability and airflow in mind, making it an excellent choice for heavier sweaters that are prone to overheating.

Choose the Simba Hybrid if you:

  • Are a light- or average-weight sleeper
  • Sleep on your side or back
  • Prefer medium-firm mattresses with a slightly softer feel
  • Are a warm sleeper or sweat a little more heavily
  • Are a restless sleeper
  • Like the hybrid design
  • Want good edge support

The Simba mattress cover is also removable and washable at 40℃.

Emma Original: body-hugging comfort

The Emma mattress is slightly firmer than the Simba Hybrid, and we've rated it as a 7 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.

This makes it an excellent choice for lighter- or average-weight people with different sleep profiles.

Since the Emma also features memory foam, which offers body-hugging comfort, it's often recommended as an orthopaedic mattress for people with back pain.

The one drawback of this body-hugging comfort is that moving around on the Emma mattress becomes a little more cumbersome.

So, we wouldn't recommend memory foam mattresses like the Emma Original for restless sleepers.

Choose the Emma Original if you:

  • Want a mattress with body-hugging support and orthopaedic properties
  • Are of lighter or medium build
  • Sleep on your side or back
  • Prefer medium-firm mattresses with a slightly firmer feel
  • Want a no-fuss mattress with a removable and machine-washable cover

The Emma Original will be less suitable if you're a pure stomach sleeper, a heavier sweater, or a restless sleeper.


But regardless of whether you choose the Emma or Simba mattress, we'd recommend safeguarding your mattress with a mattress protector - despite both of them featuring machine-washable top covers.

Waterproof mattress protectors safeguard against moisture, spills, and bacteria, and elongate the lifespan of your mattress.

  • Should you choose Emma, Eve, or Simba mattresses?

    If you're torn between the Emma Original, Eve mattress, and the Simba Hybrid, then you'll have to choose one of three very high-quality options.

    We would recommend you read our full Emma vs Simba review here, as well as our Emma vs Eve review and Eve vs Simba review.

    These will give you a lot more detail in helping you decide.

    But here a quick overview:

    • The Emma Original is a memory foam mattress with good orthopaedic properties that's well suited to lighter-weight side sleepers.
    • The Eve Original is a memory foam mattress better suited to a wider range of sleeping positions.
    • The Simba Hybrid is a hybrid mattress that's good for restless sleepers, heavier sweaters, and those requiring a little more support.

    All three mattresses come with a risk-free trial period, so you can return them for a full refund if you're not 100% satisfied.

  • Should you choose Emma, Simba, or Nectar mattresses?

    While both the Emma Original and the Nectar are memory foam mattresses, the Nectar can be regarded as more of a pure memory foam mattress.

    In terms of composition, the Nectar is an entirely different mattress to the Simba Hybrid.

    The Nectar is also much firmer than the Emma Original or the Simba Hybrid.

    It is particularly well-suited to sleepers of average weight who like a firmer feel.

    Our suggestion:

    • Choose the Emma Original if you're a lighter-weight side sleeper and want an orthopaedic mattress.
    • Choose the Simba Hybrid if you need breathability and enjoy a cooler feel when sleeping.
    • Choose the Nectar if you're of average weight and like the memory foam feel.

    The Emma Original and Simba Hybrid come with a 200-day trial period, while the Nectar comes with a 365-night trial.

    This means that you can try any of these mattresses for an elongated period of time to see if they're right for you. 

    And if they're not, you can return them for a full refund.

  • Can I buy the Emma mattress and the Simba mattress on Amazon?

    Both the Simba Hybrid mattress and the Emma mattress are available on Amazon in the UK.

    Amazon in the UK is better than other stockists or independent retailers.

    You generally get the same trial period and delivery conditions as when you buy from the mattress brands directly.

    Occasionally, you'll even get the same discounts! 

    This isn't the case with Simba but is generally true with Emma mattresses.
